# Playwright

#### 什么是Playwright？

[**Playwright**](https://playwright.dev/)由 Microsoft 构建，是一个 Node.js 库，透过单一 API，可以自动化在 Chromium、Firefox 和 WebKit 上运行的网站和 Web 应用程式。编写 JavaScript 程式码的开发人员可以使用这些 API 来建立新的浏览器页面、导航到 URL，然后与页面上的元素互动。此外，由于 Microsoft Edge 建置在开源 Chromium Web 平台上，Playwright 还可以自动化 Microsoft Edge。
